Just had blood test results back, following a repeat of feeling weak & wobbly, as happened last September/October.
I changed my sublingual B12 brand, & dropped the dose due to dietary increase, & thought it might be PA, but results for B12 came back high in range despite no supplements for 3 weeks, though I'm aware it takes 3 months for B supplements to deplete. Just been called in to doctors due to "unusual" THs, as my GP who knows I self medicate is away. He requested the B12 blood sample go to St, Thomas' for more accurate test, but don't think this was done. I wasn't given the print out for vitamin D which is low when I spoke to the receptionist, as I'd also stopped taking any additional to my prescription 800ius, now topping up with a week of 10000ius before going back to 4000. Wondering if she missed out anything else I ought to know, aside from iron & ferritin as i was only given page 1 of 5. >
I'm currently on warm weather T3 dose of 62.5mcg of T3, as free T3 was low, last test on 50mcg: 4.1 pmol/L (3.1-6.8pmol/L). Winter dose of approx equivalent of 75mcg T3, including NDT is definitely too high, & feel more exhausted on 50mcg, Fatigue's worsened over the past month as back to needing an afternoon sleep, but I don't feel as shakey.
Thanks in advance for your helpful advice!
